i think if people want to spend a fortune on a perfect museum piece thats up to them,but if you wish to ride and enjoy a bike, a basket case or not so standard bike is a good way to go. i built a 57 thunderbird a few years back wich i use on a regular bases it is matching numbers but was just a pile of bits with a lot of the correct parts missing i built the bike to my own taste with the parts i had,it has a tls front brake (its nice to be able to stop)early bonnie forks headlamp,twin 389 monobloc carbs on a iron head,rev counter, early tank pre 57 style,twelve volt electrics,slickshift gearbox and its painted non standard colours
